Organization, Consolidation and Presentation of Financial Statements [Abstract]
ORGANIZATION AND OPERATIONS	ORGANIZATION AND OPERATIONS Nature of Business Salarius Pharmaceuticals, Inc. (“Salarius” or the “Company”), together with its subsidiaries, Salarius Pharmaceuticals, LLC, Flex Innovation Group LLC, and TK Pharma, Inc., is a clinical-stage biopharmaceutical company focused on developing effective treatments for cancers with high, unmet medical need. Specifically, the Company is developing treatments for cancers caused by dysregulated gene expression, i.e., genes that are incorrectly turned on or off. The Company is developing two classes of drugs that address gene dysregulation: targeted protein inhibitors and targeted protein degraders. The Company's technologies have the potential to work in both liquid and solid tumors. The Company's current pipeline consists of two small molecule drugs: 1) SP-3164, a targeted protein degrader, and 2) seclidemstat (SP-2577), a targeted protein inhibitor. The Company is located in Houston, Texas. In addition, the company has early stage development in both protein inhibition and protein degradation. Going Concern Salarius has no products approved for commercial sale, has not generated any revenue from product sales to date and has suffered recurring losses from operations since its inception. The lack of revenue from product sales to date and recurring losses from operations since its inception raise substantial doubt as to the Company's ability to continue as a going concern. The accompanying financial statements are prepared using accounting principles generally accepted in the United States applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The financial statements do not include any adjustments relating to the recoverability and classification of recorded asset amounts and classification of liabilities should the Company be unable to continue as a going concern. Salarius will require substantial additional capital to fund its research and development expenses related to its oncology drug. Based on Salarius’ expected cash requirements, Salarius believes that there is doubt that its existing cash and cash equivalents, will be sufficient to fund its operations through one year from the financial statements issuance date. The Company intends to obtain additional capital through the sale of equity securities in one or more offerings or through issuances of debt instruments, and may also consider new collaborations or selectively partnering its technology. However, the Company cannot provide any assurance that it will be successful in accomplishing any of its plans. Acquisition and Strategic Collaboration Agreement On January 12, 2022, the Company, entered into an Acquisition and Strategic Collaboration Agreement (the “ASCA”), with DeuteRx, LLC, a Delaware limited liability company (the “DeuteRx”), pursuant to which DeuteRx agreed to sell, and the Company agreed to purchase and assume from DeuteRx, all of DeuteRx’s rights, title, and interest in and to certain assets of DeuteRx, including SP-3164, DeuteRx’s intellectual property, information and data related to SP-3164, tangible materials or reagents related to SP-3164, goodwill, rights and claims, other than certain excluded assets (collectively, the “Purchased Assets”), all as more specifically set forth in the ASCA, and assume certain assumed liabilities, upon the terms and subject to the conditions set forth in the ASCA. The Aggregate purchase price paid under the ASCA was $2.0 million consisting of $1.5 million cash payment and the delivery of 40,000 shares of the Company's common stock, valued at $0.5 million. Total cost incurred in obtaining in-process research and development technology ("IPRD") that has no alternative future use are charged to research and development expense as acquired, and presented as investing activity cash outflow on the Statement of Cash Flow. In addition, the Company agreed to pay to DeuteRx potential future milestone payments upon the occurrence of an applicable Milestone Event (as defined in the ASCA) and potential future royalty payments. A member of the Company’s Board of Directors also serves as a consultant to DeuteRx and is employed by an affiliate of DeuteRx.
